Q: Solve an equation with (almost) any numbers you like

Helka HombaGiven a string of the characters +=- where there is at least one =, insert positive integers between all the symbols and at the start and the end such that the math equations are satisfied. For example, given the input +-=-= you need to insert positive integers A through F like this A+B-C=D-...

 
7:17 PM
@Riker example pic? Doesn't seem to work on mobile
 
1 sec
 
@Riker This is disturbingly similar to Hammer's displacement editor
 
trying to make a cube
it's not working
@quartata o_O
 
except that you can't make valleys with it, only positive displacement
It automatically seams displacements together so I guess that's different
Obviously the hats are a little different...
 
me messing around ^
 
7:21 PM
Wait, how the heck did you do that shape?
It's off the ground
OK, nevermind this doesn't work the way I thought it did.
 
Curious
 
you can only place snow vertical though
it looks like a 45° angle up or more
 
@DJMcMayhem oy, stealing my taxonomist :P (I guess that's what I get for putting off creating the tag for months)
 
Haha, I was just going to ping you about that
 
oh, it was you who suggested the tag name
that's fine then :P
 
7:33 PM
what tag?
 
Wait, what is taxonomist again? Tag wiki's?
 
no
make a tag that's later used on 50 questions
 
Ah, OK.
 
do you have it already o_O
 
7:35 PM
I highly doubt we'll have 50 expression building challenges
 
you shouldn't because there's only 4 ;p
@DJMcMayhem ya never know
 
@Riker Yeah, cause I literally just started editing them in
 
lol k
 
@MartinEnder Did you see my edit on my answer?

A: We need a tag for "arithmetic expression building" challenges

DJMcMayhemI think having a tag for this is a good idea. The other solutions are great, but I'm going to throw out another one: expression-building Edit This seems to be the most popular solution, so I went ahead and created this tag. I'm going to slowly edit it into the questions that Martin has link...

 
7:40 PM
@fergusq Btw, I'm writing up a vim syntax-highlighting file for Roda
 
:o
 
@KritixiLithos Cool. Share it somewhere when it's done.
 
:O I just passed doorknob on questions
 
:o
where's the page for the top askers?
 
7:45 PM
congrats!
gotta pass martin now :P
 
Woah, and I passed Martin in
 
@fergusq Just several basic features: github.com/kritixilithos/roda.vim
 
you'll probably pass zgarb soon also
 
@DJMcMayhem what do the columns there mean? Like 363, 60, 12.8k, 1.8k
 
im porting NAGL from Python to C for muh speeds
python code was about 30 lines
C is 76

Q: Answer-Chaining - Positive divisors of a number

Mr. XcoderThis an answer-chaining challenge, so your answer depends on the one before yours. Task: Print all the positive divisors of a number x taken as input. Input: A single number x which is the number (in base 10) whose positive divisors should be printed to stdout, console or the equivalent in...

 
@DJMcMayhem I think it's just score then post count
unless that's what you meant
 
There's exactly what I meant
 
ah ok
i thought you meant score divided by post count
 
@HelkaHomba As you can see, you're head and shoulders above everyone else in quantity and quality. Your challenges average 8 points more than mine
 
7:53 PM
@KritixiLithos It seems like a good start. I myself use usually a gtksourceview-3 syntax highlighting file. It contains a list of keywords and a currently out of date list of functions, in case you need them in your file.
 
Muahaha
 
@NewMainPosts gonna try this in matl @LuisMendo, looks like a good challenge for that
@HelkaHomba question: do you also type from mobile?
because that would make DJ even more your sock
 
@Riker Like for writing challenges? Only very rarely
 
no, for chatting
 
Oh, sure, sometimes
Like now
 
7:57 PM
:O
@DJMcMayhem is @HelkaHomba confirmed
they chat from mobile
they write challenges
they both play minecraft
 
@Riker I'd be very impressed if Helka had enough time and dedication to be two separate top users (and have conversations with himself to avoid suspicion) :P
 
> if Helka
 
@Riker Don't lots of people?
 
you mean "if I"
@HelkaHomba well yeah but you're still socks ;p
 
@HelkaHomba Prove I'm not your sock, what number am I thinking of?
 
7:59 PM
that proves nothing :P
he knows exactly what number you're thinking of and thus could just guess a different one
 
Pi*e
 
@HelkaHomba What? How? That's impossible.... I uh yeah that's right
 
lol
@LuisMendo @flawr how can I end the program and output immediately in matl?
 
@Riker output is D, I don't know of an exit though
 
hm thanks
 
8:06 PM
Although % is comment
 
thanks
that works
 
Do you know about Z\?
 
no?
 
It's the divisors built-in
 
Hmm, apparently in JS /[^=]*/g matches ++= three times: once with ++, once before the =, and once after the =
That's unhelpful
 
8:07 PM
Courtesy of yours truly:
in MATL CHATL, Oct 22 '16 at 15:24, by Luis Mendo
@DJMcMayhem Z\ seems like a good choice (divisors are related to modulo, which is the \ symbol). For negative inputs Jelly gives the same as for positive. I think I'll go with that
 
@DJMcMayhem :/ can't use it though, builtins not allowed
 
Aww, that's too bad. You could do :tGw\~) though
 
hm, thanks
 
@Riker You can produce an error. But then you don't get implicit output
@Riker Good choice :-P
 
got it :D
with comments + DJ's solutoin

RikerAnswer 3: MATL, Distance 15 :tGw\~) %n=int(input()) %i=1 %div=[] %while (i<=n): % if n % i == 0: % div.append(i) % i+=1 %print(div)

 
8:15 PM
When was that challenge posted?
 
I want to see a brain-flak answer really badly. That would be really cool
 
Darn @NewMainPosts, I was relying on you to let me know about new challenges
 
Ah, great! :-) @Riker
 
NewMainPosts is a bit slow right now
 
@DJMcMayhem Lets make it happen
 
8:18 PM
I gtg now though, see y'all
 
This answer chaining is going to die horribly as more gets added
 
@ETHproductions a whole ago
 
It'll be really hard. We'll need a bunch of people basically donating free brackets in their answers
 
While
NMP already got it :p scroll up
 
8:19 PM
@LliwTelracs yeah, this isn't a good objective for this format really
 
@DJMcMayhem We can do it, I'm writing up the brain-flak code now and then I can try to make a bunch of solutions that add brackets
 
Darn @myeyes, I was relying you to let me know when @NewMainPosts posted anything
 
15 char limit to changes... as it gets longer
we need a whitespace answer since apparently whitespace doesn't count towards the char limit
 
@ETHproductions brb, changing name to myeyes
 
@AdmBorkBork do you see them with your special eyes?
 
8:22 PM
It's actually Mye Yes.
 
....is PPCG offline for anyone else?
Now it's back
 
read-only mode
 
Damnit maintenance!
 
It is their fault. They even said so
 
@ETHproductions it's giving me the "it's not you it's me"
 
8:25 PM
ah yeah, now it does
 
First it was "we are currently offline for maintenance", then it was read-only mode for 30 seconds, now it's "it's not you, it's us"

I got server error, can't find /
 
Maybe they're doing some HTTPS work
 
8:27 PM
Stack is offline. Working on it now.
Here's the tweet too.
 
Back in read-only now
 
Back in read-write now.
 
Hmm, apparently this was not a planned thing
 
Not for me
 
Hard refresh: Ctrl+F5.
It's probably cache.
 
8:31 PM
I mean I planned it >:)
 
"yay" :(
 
@LuisMendo can you clarify what \ does?
Or @DJMcMayhem
 
@Riker Lol, you don't understand your own answer
\ is modulus
 
No I did
But got confused when he commented
Emphasis on "did", not "do" :p
 
@DJMcMayhem Here is the shortest code I can make to do the task
 
8:37 PM
Wow, writing all these tests takes a long time
 
@Riker You should post an explanation of your code to clear up confusion
@WheatWizard Ouch. That'll be tough to get. If you manage to make it, I'll bounty it :)
 
I might need the help of at least one more person
 
Part of what would make that so impressive is the teamwork you'll need to get it working
 
Re the screenshot, I've noticed that while Chrome didn't remove the profile name from the toolbar, they did at least remove the button look of it. Or is it just because it's on Mac?
 
@DJMcMayhem will do when not mobile
 
8:57 PM
@JanDvorak Just Mac
> "Mac"
 
ah, bummer. I'm sticking to Firefox then. Thanks.
 
is there a python1

A: When was this language released?

Sp300015 years, Python Versions: 0.9.1, 2.0.0, 2.2.0, 2.2.2, 2.5.0, 2.5.1, 3.0.0, 3.1.0, 3.1.3, 3.2.1, 3.3.0, 3.3.3, 3.4.0, 3.5.0 and 3.6.0a4. Versions not linked can be found on the downloads page. The release date of 0.9.1 can be found here. Unfortunately I had to skip a large bunch of years due to...

 
Maybe Python 1 met the same fate as IPv5 did
 
Nice
 
9:00 PM
can i turn a 1d array in c into a 2d array that's split by a delimiter, eg "qwe0asdf0zxc0" -> {"qwe", "asdf", "zxc"}?
 
@betseg Yes.
 
define "2d array" in C
 
@JanDvorak an array of arrays
@DJMcMayhem how
 
Does anyone know how to run Python 1?
 
You can have an array of pointers. If you want an array of arrays, you need to know the width in advance.
 
Yeah I was hoping not to ahve to compile it myself. Thanks
 
@JanDvorak hm, i think i can do that by looping strchr and finding the longest jump
 
It might be easier to go with an array of pointers
 
If you don't want to have to compile it just write the binaries by hand.
 
@betseg I was intentionally trying to be unhelpful. Yes. You can. How is a much harder question, You'll probably have to loop through it and figure out the logic
 
9:04 PM
strchr is a useful function for that, yes

A: Sandbox for Proposed Challenges

Jan Dvorakfind the set of Sets in a subset of Set. code-golf the Set game is a one-player card game using a deck of 81 cards. Derivatives - primarily those that remove most of the cards - exist. We shall be using one of such derivatives today. a card in the deck is defined by four properties of the symb...

 
@DJMcMayhem thanks for being a rubber duck?
 
CMC: given as input one of the chars ABCDEFG. output its index in that string, without using index functions. You may optionally output -1 instead of 7 for . (or 0, if your answer is 1-indexed)
 
->x{x.ord-64}
 
9:15 PM
@ETHproductions Related.
 
@JanDvorak I think you missed the .
 
ah, drat
 
@AdmBorkBork ;-)
 
&'A-.@
 
->x{(x.ord-64)%47}
 
9:16 PM
Befunge 98
 
C, 25 bytes: f(i){return i^46?i-65:7;}
 
Can we treat it as having received the charcode if the language doesn't accept strings as input?
 
@LliwTelracs Sure, if there's no other way of inputting a char, that's fine.
 
@LliwTelracs if that's the language default...
 
Wtf.
Since when does 8GB of RAM cost $65?
 
9:18 PM
Is that too much for your wallet?
 
I remember it being something like $30 a couple of years ago
 
Oops ~'A-.@
 
@ETHproductions 20 bytes in V
 
@Mendeleev a) that's SODIMM, b) that's DDR3
 
9:19 PM
@Riker no idea, sorry
 
@Mendeleev it's actually free: downloadmoreram.com
 
@AdmBorkBork yes, and? SODIMM wouldn't be that much more expensive, and I would think that DDR3 would be cheaper
@betseg Kek
 
@JanDvorak Ooh, I think you can do %26-13 to remove the parentheses
 
ah, true
 
Oh duh, just do %13 :P
@DJMcMayhem That looks complex
 
9:22 PM
 
@Mendeleev Manufacturing for DDR3 is ramping down, so it's more scarce.
 
@ETHproductions Yeah, it's kinda weird
 
@AdmBorkBork Ehh
It's used a LOT in mobile devices
 
That's why I really enjoy V-golfing because it's either super competitive or really weird and hacky
 
Laptops too
 
9:23 PM
12 bytes in cardinal but that's mostly due to receiving it as charcode
 
@DJMcMayhem Hmm, it outputs 0 for both . and A
I wish I knew V so I could figure out how it works
 
Retina, 6 bytes: T`.L`d (1-based, uses 0 for .)
 
TL;D... what?
 
@LliwTelracs OK, cool. I was going to say that it doesn't work for ., but that was your previous answer
 
@ETHproductions can i output in binary?
 
9:27 PM
Um, sure?
 
@ETHproductions huh. Not sure why that is
 
@BasicSunset explanation?
 
@JanDvorak It transliterates from .ABCDEFG.... (the whole alphabet) onto the digits 0123456789
 
It Transliterates from . + LETTERS to digits
 
Is that language documented somewhere? I'd like to use it once.
 
9:29 PM
@ETHproductions I know what was wrong. Fixed now! Try it online!
 
Ah, thanks
 
@DJMcMayhem Nice :-) Now I'm wondering what Í does
 
It signals to the search command / to not treat certain characters as special. So by default, a . will match any character, but \. matches a literal dot. Í forces all characters other than \ and / to be treated literally
 
9:34 PM
I can't even sandbox posts without downvotes every time
:P
 
@ETHproductions Brainfuck, 54 bytes. Try it online!
 
@ETHproductions Would you like a more detailed explanation?

this is borking me so much
 
)
fixed it for you
 
i couldn't handle that amount of stress

I've got a friend IRL who's a programmer and absolutely hates unbalanced parens. With a passion. Like, if I send him a text message that has an open but no close paren, he'll actually go to the effort of sending a text message back containing a close parens before he'll respond in a separate message.
 
@ETHproductions Cool, I've written it up. Is ten lines in chat obnoxious? Should I link it somewhere else instead?
Wait, Nevermind I'll just link it from the vim room

It appears this submission doesn't take n as an input, but requires a hard coded variable. If that's correct then I'm afraid this is not valid according to meta consensus. — Stewie Griffin 22 secs ago
^^ Am I right here?
 
if you assessment of the code is correct, then yes
I don't know swift, so I can't say for sure
also, I hadn't seen that challenge. Really good idea for a CnR
I keep on thinking that we've surely used up all of the good ideas for CnRs but you guys keep on surprising me
